Abstract: A flow regulator is disclosed for controlling liquid flow, for example, from a supply source to a receiving tank according to the liquid level in the tank. Specifically, a fluid interaction device communicating with the receiving tank causes a fluid pressure signal to be developed in response to departure of the liquid in the tank from a predetermined level. A differential pressure responsive valve adjusts liquid flow from the supply source to the receiving tank in response to the fluid pressure signal. Several embodiments and other features including a bypass for enhancing stable flow and a preferred valve structure are disclosed.A beverage dispensing system incorporating the aforesaid flow regulator is also disclosed. A cold carbonated liquid is continually circulated past dispensers from a pressurized chill tank having a carbon dioxide atmosphere. The flow regulator admits further liquid to the system from a supply source whenever liquid is tapped from the system by the dispensers.

Abstract: A ski board including an elongated riding platform, a pair of mounting brackets, a pair of skis, and resilient means for joining the skis. The elongated riding platform is of a length sufficient to permit a person to stand on the platform with one foot in front of the other. The mounting brackets are attached to the underside of the elongated riding platform in longitudinally spaced relationship. The skis are attached to the mounting brackets in longitudinally aligned relationship for pivotal movement about horizontal axes. The resilient means for joining the skis connects the rear edge of the leading ski to the tip of the trailing ski. With this construction, the trailing ski will track the leading ski over uneven terrain without the possibility of bottoming out.

Abstract: A monitoring system is comprised of an elastomer balloon housed in a rigid cage having a plurality of windows which is designed to continuously indicate the state of collapse or expansion of the internal cuff or cuffs of an encotracheal tube. This balloon monitor is interconnected in series with the pneumatic channel through which the cuff or cuffs are inflated. The volume of the balloon may be observed visually with reference to its filling the cage enclosure denoting thereby its state of inflation and therefore, also that of the endotracheal cuff. Calibration of the balloon monitor provides means for accurately observing both the volume and pressure of air in the system. Therefore, visual inspection of the balloon monitor indicates by reason of the calibration the prevailing level of pressure in the patient's endotracheal cuff.

Abstract: An improved snap-on-clamp is provided for securely fastening one object to another, such as fastening a flexible hose about a pipe, a nipple, or the like, and includes an open-ended, substantially annular band having formed at its ends a pair of opposed, interlockable members. Each interlockable member includes an arcuate jaw having a plurality of teeth which interlock with the teeth of the opposed member's jaw when the interlockable members are interengaged and the clamp is in a clamping position. Each interlockable member further includes resilient bias means spaced apart from its respective jaw to provide opposing forces to the interlocked jaws so that the plurality of teeth are forced together, thereby preventing separation of the interlockable members other than by transverse shear.

Abstract: An apparatus for lifting and transporting an invalid from a wheelchair to a bed or other location and back including a sling suspended from a motor driven winch for raising and lowering the sling. The winch is suspended from a motorized traverse mechanism for reciprocably moving the winch and sling along a horizontal track attached to the ceiling of a room for transporting the invalid.

Abstract: The invention provides an automatic cancelling turn signal for a motorcycle or the like having a transmission with at least two forward speeds which operates by cancelling the turn signal in response to an upshift. The apparatus comprises left and right turn signal lights, switch means for selectively activating the left or right light, and inactivating means for inactivating the lights responsive to the shifting of the transmission from a lower gear to a higher gear. Means are also provided for including a four-way flasher in a turn signal system.

Abstract: A shallow relief printing plate is disclosed having a polymerized layer of less than about 0.020 inch and which includes an array of small protuberances in non-image or background areas to prevent bottoming. Photopolymerizable elements, as well as processing techniques, are also disclosed for making such printing plates.

Abstract: An apparatus for winding stock in coil fashion. The apparatus includes a base, a variable speed motor, a speed selection control unit, a coil guide, and clutch means. The variable speed motor is mounted on the base and operatively joined through a first gear box to a drive shaft equipped with a reel for taking up the stock. The speed selection control unit regulates the speed of the motor having monitoring means responsive to movement of the stock at a point remote from the reel. The monitoring means instantaneously signals the motor to slow in response to momentary slight increases in the speed of the stock at the remote point as the diameter of the stock on the reel builds to maintain the speed of the stock at the selected speed on the control unit. The coil guide is operatively joined through a second gear box to the first gear box for rotation and reciprocation to direct the stock onto the reel being carried on a support shaft linked to the second gear box through reciprocal camming means.

Abstract: A double cuff for endotracheal tubes is designed with two inflatable balloons, shaped to fully occupy the spaces above and below the open larynx. The two cuffs have a common inflation channel and therefore after their inflation are in free communication with each other. The lower cuff with its thin non-elastic walls rests in the upper trachea, applying a pressure against the walls of the upper trachea and subglottic structures determined by the behavior of an upper cuff whose walls are elastic. This elastic cuff occupies the space immediately above the larynx and extends slightly into the pharynx. Elastic properties of the upper cuff confer, in effect, a pressure relief system to the lower non-elastic cuff as a result of their interconnection through the common inflation channel.

Abstract: An esophago-pharyngeal airway having at least one inflatable cuff for sealing the nasal passage by urging the soft palate against the posterior nasopharyngeal wall and sometimes another inflatable cuff engageable with the wall of the esophagus to prevent ventilation of the stomach and possible aspiration of the stomach's contents depending upon the selected use. Either or both of the cuffs may be continuously inflated during use of the airway or may automatically inflate and deflate with each respiratory cycle to insure non-traumatic extubation when a tracheal tube is substituted for the esophago-pharyngeal airway. An air tube extends through one of the cuffs and a gastro-esophagus tube extends through both of the cuffs.

Abstract: A dynamometer is provided having a housing mounted to allow at least partial rotational displacement about its longitudinal axis, with a frictional engaging means connected thereto for engaging the external surface of a rotatable drum. This drum, which is mounted within the housing, is coupled to the prime mover so that the power of the prime mover may be determined by measuring the torque transmitted via the engaging means to the housing. Coolant is circulated through the interior of the drum while the drum is rotating within the housing, thus providing a dynamometer which is not only accurate but is easily disassembled for maintenance. The dynamometer also includes a hydraulic brake mechanism which can be regulated without a variation in the flow rate of the working fluid.

Abstract: A rear view cycling mirror is disclosed comprising a case housing a mirror adapted to be strapped to the wrist of a cyclist or attached via a clip to the bicycle. The mirror is mounted on the inside face of the case cover which is hinged to the base of the case by a universal ball joint. This joint provides maximum adjustability to the cyclist. The strap or clip is inserted through a slot in a dropped portion of the base.
